Edit: Now I have one 80 of every class.

That's probably going to stay my whole team from here on out, at least until new classes get added in future expansions. My goal was simply one of every class so I get to play with it all. Great number right now, since I only need to work with 2 full teams to get everyone equipped. I just need to decide how I intend to structure the second team. I think I'm going to give a DK (tank), warrior, rogue, hunter, druid (healer) team a shot for the challenge. Besides questing, I haven't really had a challenge with a melee-heavy team yet. Good compliment to my ranged-based team that I have now.
